Professional Applications & Engineering Value
Engineered for demanding industrial applications, these M12 hex head screws deliver exceptional performance in heavy machinery, structural steel connections, and equipment manufacturing. The Class 10.9 high-tensile steel construction provides critical resistance to vibration loosening and dynamic loading, while the coarse thread pitch ensures reliable engagement in both metallic and composite materials. The black oxide surface treatment offers enhanced corrosion protection for outdoor or chemically exposed environments. With full threading along the 45mm length, these metric fasteners maintain consistent clamping force across thick assembly sections, making them ideal for construction, automotive, and industrial maintenance applications where failure is not an option.
Specification Summary & Compliance
Manufactured to ISO 4017/DIN 933 standards with Class 6g thread fit tolerance ensuring precise dimensional accuracy. The M12x1.75mm coarse thread configuration provides optimal thread engagement for general purpose applications. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations guarantees environmentally responsible manufacturing. Right-hand threading and external hex drive design conform to international metric fastener specifications for universal compatibility.
